Watch credits on Apple TV on Roku device

Credits are part of a TV show or movie. Stop defaulting to cutting off parts of the TV shows and movies we watch.

I want to change my default option that the credits play through, fullscreen, until the end. And *I* will choose to turn them off. Not you.

How do I do that?

(Also: your prefab tags and topics do not cover this. As if no one chooses to watch Apple TV on a home AV system with a more comfy chair than my computer area.)
